I'm not sure if she turned it in, I thought she said she was going to continue it, but it quickly became just like any other talking head and the in-story reasons for it were immediately thrown away. I think, even in the pilot, that the context of the talking head was rather sloppy with the parents saying things about their daughter that they definitely should not say to her face.

Writers like talking heads because they simulate the "third-person omniscient" viewpoint you can get in written stories. The ability to pull out any character's thoughts at any time is useful from a storytelling perspective and it can be used effectively for jokes. I find it lazy some of the time though.
